Unsatisfied dependency expressed through field 'mongoTemplate'

具體情況是我的聚合項目,在使用

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-mongodb</artifactId>
           <!– <version>2.1.5.RELEASE</version>–>
        </dependency>

遇到報錯,大概就是連接linux 在一段時間,大概8分鍾左右,會自動斷開,下次第一次刷新會報錯,之后就會好了

　自己創建一個demo ,使用的高版本后,並沒有此問題,可是老項目中,主依賴中我修改了mongodb的版本,問題依然存在,講mongodb單純分出一個項目后,這個問題可以解決.

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.3.1.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
</parent>

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-mongodb</artifactId>
</dependency>

於是只能單獨將mongo分出來了,在主項目中引入配置文件

 

 此時啟動會遇到問題:

Unsatisfied dependency expressed through field 'mongoTemplate'

疑惑,測試的demo里面也是這樣寫的,沒有出現此問題,為何遷移到主項目中mongotemplate沒有注入

 

原因:

去掉主項目的啟動類中的兩個mongoauto配置,就解決了這個問題.
